Solano County Superior Court Judge Robert Bowers declared the mistrial after the jury announced it was deadlocked after just three hours of deliberations. Nine jurors felt Pearsall was guilty of the DUI charge; three felt he was guilty of the hit-and-run charge.

Both charges are misdemeanors with a maximum jail sentence of six months.

Solano County Deputy District Attorney Rashaan Jones said afterward the case will be re-tried. A trial-setting date was scheduled for May 2, in Bowers' Fairfield courtroom.

The case stems from Pearsall's arrest in July 2012, after he allegedly struck a parked car in a shopping center parking lot and later bumped a police car in front of his house in the 200 block of El Camino Real in Vallejo.

Pearsall, 68, didn't dispute the evidence that he drove while impaired. Instead, he fought the charges based on his belief that he didn't know -- and wasn't properly warned -- about the medication's intoxicating effects.
